Our Body Did you know our DNA knows how to grow a new body, as it did it once before and continues to do every day. An average adult sheds close to 500 million skin cells daily, replenishing the outer layer of skin completely in two to four weeks. The body’s detoxifier, known as the liver, aids us by getting rid of various contaminants from our systems and staying immune to such toxins by renewing its cells every 150 to 500 days. We cannot reverse ageing, but we are committed to age youthfully and finding the best version of you in all stages of life.
